Describe the chart you want in ordinary language — “bar chart of sales by region” — and the tool produces it without scripting or menu hunting.
The assistant recommends visualisations that fit the columns and data types you uploaded, which helps when you are not sure which view tells the story.
Supports common business visualisations including bar charts, line graphs, pie charts and scatter plots.
The platform states that only metadata is processed server-side and that the actual data rows remain with the user, which reduces exposure of sensitive figures.
